Although he has lost many of his best traders, been forced to cough up more than $1 billion in fines and had to reinvent his once-storied hedge fund, Steven Cohen is not spurning the limelight these days.

Cohen, whose now-defunct firm SAC Capital pleaded guilty to insider trading charges last year, recently hosted a debate at his Greenwich mansion between former U.S. Treasury Secretary Lawrence Summers and the dean of Columbia Business School Glen Hubbard, according to an online report on Fox Business by Charlie Gasparino, a senior correspondent for the network known for his scoops on Wall Street.

The off-the-record event was sponsored by the Stamford Chamber of Commerce. Jack Condlin, president of the chamber, could not be reached for comment.

It is shaping up to be a busy summer for Cohen. A week ago, the New York Times reported that he and his wife took part in a charitable event in the Hamptons home of comedian Jerry Seinfield. It also said Cohen, who collects art, was in attendance at Art Basel in Switzerland in June and that the family enjoyed a vacation this summer sailing on a yacht off the Greek islands.

More importantly, the July 30 article reported the Greenwich resident is reaping huge amounts of money at his newly named firm, Point72 Asset Management.

The company, which is based in the former SAC office in Stamford, has netted a profit of nearly $1 billion over the first six months of this year, according to the story, which cited unnamed sources.

The firm, which once had 1,000 employees, now employs about 850, according to the New York Times.

According to the story by Gasparino, the debate at Cohen's house featured some head-turning remarks by Summers. The former economic adviser for President Barack Obama was said to have criticized a recently released report by Federal Reserve chairwoman Janet Yellen.

Quoting unnamed sources, Gasparino wrote that Summers was heard as saying that Yellen "shouldn't be trying to value" subsectors of the stock market.

The comments, he added, surprised the crowd of roughly 100 "investors and business types."

Summers coveted the job of Fed chief before dropping out of the contest after significant political opposition.

The partnership with the Stamford chamber on the event was yet another sign of Cohen's continuing involvement with the city. His foundation has given $5 million to the construction and maintenance of a fountain and outdoor ice-skating rink at Mill River Park.

His firm has also continued to sponsor events organized by the Downtown Special Services District. This summer, Point72 Asset Management is credited with supporting "Street Seats," an outdoor sculpture exhibit. And in a move that will likely make children across the city smile, Cohen's company will once again finance Stamford's annual pre-Thanksgiving Day tradition: a balloon inflation party on Nov. 22.
